The purpose of this study was to analyze the relationships among participation degree and pattern on leisure sports and the characteristics of health care. The subject of the study was selected by multi-stage stratified cluster random sampling among the sports center and sports club to participate sports program whose age were 20-60 year old among inhanitant the Seoul metropolitan area. The data were collected through a questionnaire adapted from Payne and Hahn's (1986) ‘Understanding Your Health-A personal profile; Evaluating Your Health’. The pilot test was executed after the questionnaire was translated into Korean. The statistics employed the study were validity and reliability test, χ2 verification, frequency, ANOVA, multiple classification analysis, ANCOVA and Multiple Regression Analysis. The results that were derived form these processes were as follows. 1. There is partial difference according to the participation patterns of Leisure Sports. There were differences according to stress managent, physical fitness, social relationship, nutrition, drinking, smoking, drug use care, health comsummersion. 2. There is a partial difference according to the dimensions of Leisure Sports. There were differences according to physical fitness, social relationship, nutrition, drinking, smoking, drug use care, heredity.

Purpose: This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). Methods: This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between 2005 and 2010. Patients received stem cells from MRD (n=33), URD (n=46), or UCB (n=41). Results: Neutrophil and platelet recovery were significantly longer after HSCT with UCB than with MRD or URD ($p$ <0.01 for both). In multivariate analysis using the MRD group as a reference, the URD group had a significantly higher risk of grade III to IV acute graft-versus-host disease (GVHD; relative risk [RR], 15.2; 95% confidence interval [CI], 1.2 to 186.2; $p$=0.03) and extensive chronic GVHD (RR, 6.9; 95% CI, 1.9 to 25.2; $p$ <0.01). For all 3 donor types, 5-year event-free survival (EFS) and overall survival were similar. Extensive chronic GVHD was associated with fewer relapses (RR, 0.1; 95% CI, 0.04 to 0.6; $p$ <0.01). Multivariate analysis showed that lower EFS was associated with advanced disease at transplantation (RR, 3.2; 95% CI, 1.3 to 7.8; $p$ <0.01) and total body irradiation (RR, 2.1; 95% CI, 1.0 to 4.3; $p$=0.04). Conclusion: Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.

Caspase 3, a member of cysteine protease family, is well known as a major apoptosis effector and is involved in cell death as a result of ischemic diseases such as stroke and myocardial infarction, therefore the inhibition of caspase 3 may protect those apoptotic cell damages. During the high-throughput screening of the compounds from the Korea Chemical Bank, berberine derivatives (A and B), an isoquinoline alkaloid, have been identified as potential inhibitors for caspase 3. Based on this finding we carried out molecular modeling study to identify the pharmacophoric elements of berberine structure which interact with a substrate-recognition binding site of caspase 3 and came up with several novel scaffolds. In this report, we will discuss the molecular modeling, syntheses and the enzyme inhibitory activities of these novel compounds.

Recently the idea of gender role has changed. The men have been interested in fashion and beauty considered feminine area. On the contrary, many women superior to men are showing up in every respect. These changes made us think customer`s gender in marketing research not sex in the future. This study is investigated there are any difference between male and female in recognizing brand personality of Family Restaurants targeting undergraduate school students with gender role identity. The results showed there is difference between social psychological genders and sex. In the case of sex, there is no difference between male and female at the results of discriminant analysis. However there is difference significantly between socialpsychological genders. Also hit ratio is 72.2%, which shows it has good judgement.

이 연구의 목적은 코로나19로 인한 서울 소재 한 5성급 호텔 연회부서의 변화된 조직문화를 내부자의 관점에서 조명함으로써 향후 유사한 환경 발생 시 이를 대처할 수 있는 방안을 모색하는 데 있다. 이를 위해 한 5성급 호텔 연회부서 종사원들을 대상으로 질적 사례연구를 수행하였다. 이 연구의 결과를 간략하게 제시하면 다음과 같다. 첫째, 코로나19 이후 타부서 근무로 인한 업무유연성이 강조되었고, 핵심인력의 지속적인 이탈과 종사원간의 소통 부재 등 호텔 근무환경의 크게 변화되었다. 둘째, 코로나19에 맞서는 호텔경영전략으로 종사원들의 업무에 대한 심리적 부담이 가중되었다. 이 연구의 결과는 코로나19로 인해 변화된 서울 5성급 호텔 연회부서 조직문화를 조명함으로써 호텔 조직문화에 대한 이해와 개선을 위한 이론적 및 실증적 토대를 제공할 것이다. The purpose of this study is to find ways to manage with similar environmental outbreaks in the future by examining the changed organizational culture of the five-star hotel banquet department in Seoul due to COVID-19 from an insider s point of view. To this end, a qualitative case study was conducted on employees of the 5-star hotel banquet department. The results of this study are briefly presented as follows. First, work flexibility has been emphasized due to work in other departments since COVID-19 and the hotel working environment has changed significantly such as the continuous retirements of key personnels and the lack of communication between employees. Second, the hotel management strategy against COVID-19 increased the psychological burden on employees work. The results of this study will provide a theoretical and empirical basis for understanding and improving hotel organizational culture by examining how the organizational culture has been changed by COVID-19 in the 5-star hotel banquet department in Seoul.

Multiferroic (La, Mn)-codoped BiFeO$_{3}$ thin films were deposited on Pt(200)/TiO$_{2}$/SiO$_{2}$/Si(100) substrates by a chemical solution deposition method. The coated films were annealed at 550 $^{\circ}$C for 30 min under nitrogen atmosphere. It was found that the (La, Mn)-codoped BiFeO$_{3}$ thin films exhibited good ferroelectric properties, such as improved leakage current density and \textsl{P-E} hysteresis characteristics. The leakage current density of 6.0 $\times$ 10$^{-6}$ A/cm$^{2}$ for the 7.5-mol\% La- and 1.5-mol\% Mn-codoped BiFeO$_{3}$ thin film is about seven orders of magnitude lower than that of BiFeO$_{3}$ thin film at an external electric field of 100 kV/cm. It also exhibited a well-saturated hysteresis loop with a remanent polarization (\textsl{$P_{r}$}) of 53 $\mu$C/cm$^{2}$ at room temperature. The improved leakage current and ferroelectric properties in the (La, Mn)-codoped BiFeO$_{3}$ thin film can be attributed to the La and Mn doping, that may be responsible for a reduction in oxygen vacancies.
